7. Depreciation to a Salvage Value of 0. For tax purposes an item may be depreciated
over a period of several years, n. With the straight-line method of depreciation,
each year the item depreciates by 1/nth of its original value. With the
double-declining-balance method of depreciation, each year the item depreciates
by 2/nths of its value at the beginning of that year. (In the last year it is
depreciated by its value at the beginning of the year.) Write a program that
(a) Requests a description of the item, the year of purchase, the cost of the item,
the number of years to be depreciated (estimated life), and the method of
depreciation. The method of depreciation should be chosen by clicking one
of two command buttons.
(b) Displays a depreciation schedule for the item similar to the schedule shown
in Figure 5-16.
Description: Computer

8. The Twelve Days of Christmas. Each year, Provident National Bank of Philadelphia
publishes a Christmas price list. See Table 5.8. Write a program that
requests an integer from 1 through 12 and then lists the gifts for that day along
with that day’s cost. On the nth day, the n gifts are 1 partridge in a pear tree, 2
turtle doves, . . . n of the nth item. The program also should give the total cost
of all twelve days. As an example, Figure 5-17 shows the output in the picture
box when the user enters 3.

The gifts for day 3 are
1 partridge in a pear tree
2 turtle doves
3 French hens
